David
Psalm 98:1ESV·traditional attribution

Oh sing to the LORD a new song, for he has done marvelous things! His right hand and his holy arm have worked salvation for him.

John Calvin Reformed @genevareformer

PSALM 98 This psalm has a great resemblance to the ninety-sixth, not only in matter, but language. The great scope of it is to show that the glory of God would be illustriously displayed in the spread of the knowledge of his name throughout the world, both from the more ample fulfillment which would be given upon the manifestation of the Savior, to the promises...

C.H. Spurgeon Reformed Baptist @princeofpreachers

O sing unto the Lord a new song; for he hath done marvellous things. We had a new song before (Ps 96:1-13) because the Lord was coming, but now we have another new song because he has come, and seen and conquered. Jesus, our King, has lived a marvellous life, died a marvellous death, risen by a marvellous resurrection, and ascended marvellously into heaven.

Matthew Henry Presbyterian @wholebiblehenry

We are here called upon again to sing unto the Lord a new song, as before, Psa 96:1. "Sing a most excellent song, the best song you have." Let the song of Christ's love be like Solomon's on that subject, a song of songs.
